Disable PIE for MIPS ubldr
When performing buildworld for MIPS with PIE enabled, the build fails
with "position-independent code requires '-mabicalls'" message.

Disable PIE for powerpc bootloaders.
Bootloaders for powerpc are not built as position independent
code. Since bsd.prog.mk is used for building, when PIE is enabled,
the PIE flags are added and that causes the build to fail.
Adding MK_PIE=no stops bsd.prog.mk from adding PIE specific flags.

EFI loader: Don't free bcache for DEVT_DISK devs
Booting on an EC2 c5.xlarge instance, this reduces the number of I/Os
performed from 609 to 432, reduces the total number of blocks read
from 61963 to 60797, and reduces the time spent in the loader by 39 ms.
Note that b4cb3fe0e39a allowed the bcache to be retained for most of
the boot process, but relies on mounting filesystems; this commit
allows the bcache to be retained at the start of the boot process,
before the root filesystem has been located.
Currently, the only thing that prevents a functioning 64-bit FICL build is
a few integer types that were intended to be fixed-width.
Changing them to C99 integer types allows building a functioning 64-bit
FICL.
While this isn't applicable to the default settings of any in-tree loaders,
it is necessary for a future Petitboot loader, due to the requirement that
it be compiled as a 64-bit program.
Adjust a couple of printf() lines that deal with dumping out addresses
to cast to uintmax_t.
This allows building a 64-bit libofw for use in things like a future
Petitboot loader for PowerPC64, and other FDT platforms that require
a 64-bit loader binary and want to use forth.

libsa: Remove conflicting .global/.weak directive
LLVM12 complains if you change the symbol binding:

None of the other architectures mark the libsa _setjmp as weak so

loader: zfs_probe_dev should pick first matching zfs pool
During devswitch probe, we pick boot pool based on boot disk, if the boot
disk happens to have multiple pools in freebsd-zfs partitions, the current

way at that stage to test, the more logical approach would be to pick
first matching pool.
This patch is assuming we do pass pool guid pointer with guid value 0,
this will help us to determine, if the guid value is already set or not.
The general suggestion would be not to share disk between different pools.

Create CFLAGS_EARLY.file for boot loader.
Some external code requires a specific set of include paths to work
properly since it emulates the typical environment the code is used
in. Enable this by creating a CFLAGS_EARLY.file variable that can be

stand programs may get in the way. Code that uses this feature has to
tolerate the normal stack of inclues being last on the list (and
presumably unused), though.
Generally, it it should only be used for the specific include
directories. Defines and that sort of thing should be done in the
normal CFLAGS variable. There is a global CFLAGS_EARY hook as well for
